If:
[tex] \frac{Boys}{20} = 0.45[/tex]
Soon:
[tex]\frac{Boys}{20} = 0.45 \to Boys = 20*0.45 \to \boxed{Boys = 9}[/tex]
Therefore: (It's not a boy)
Students = 20
Boys = 9
girls = ?
[tex]Girls + Boys = Students[/tex]
[tex]Girls + 9 = 20[/tex]
[tex]Girls = 20 - 9[/tex]
[tex]\boxed{Girls = 11}[/tex]
Answer: (Describe the likelihood of not choosing a boy)
[tex] \frac{11}{20} = \boxed{\boxed{0.55}}\end{array}}\qquad\quad\checkmark[/tex]
